American Institute of Mathematical Sciences Acta Medica Okayama 1078-0947 40 6 2020 Axisymmetric traveling fronts in balanced bistable reaction-diffusion equations 3981 3995 EN Masaharu Taniguchi Research Institute for Interdisciplinary Science, Okayama University For a balanced bistable reaction-diffusion equation, the existence of axisymmetric traveling fronts has been studied by Chen, Guo, Ninomiya, Hamel and Roquejoffre [4]. This paper gives another proof of the existence of axisymmetric traveling fronts. Our method is as follows. We use pyramidal traveling fronts for unbalanced reaction-diffusion equations, and take the balanced limit. Then we obtain axisymmetric traveling fronts in a balanced bistable reaction-diffusion equation. Since pyramidal traveling fronts have been studied in many equations or systems, our method might be applicable to study axisymmetric traveling fronts in these equations or systems. No potential conflict of interest relevant to this article was reported.
